MACHINEFOR FILING SHOE-HEELS.

SPECIFICATION forming part of Letters Patent No. 292,363, dated January22, 1884. Application filed November 14, 1883. lNo model.) Q 7 To 00%whom it may concern:

Be it known that I, HENRY F. Roomy, of Randolph, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Machines for Filing Shoe Heels and Bottoms; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which'will enable others skilled in theart to which it appertains to make .and'use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which Figure 1 is a perspective view of myimproved machine for filing the heels and bottoms of Shoes. Fig. 2 is avertical section of the same. Fig. 3 is a detail view of the shoeholding clamp, and Fig. 4 is a view of the shoe-jack.

Similar letters of reference indicate corresponding parts in all thefigures.

My invention has relation to machines for filing or grinding the heelsand bottoms of shoes and boots; and it consists in the improvedconstruction and combination of parts of the same, as hereinafter'morefully described and claimed.

In the accompanying drawings, the letter A indicates an upright postmounted upon a base, B, and forming a transverse perforation,

at the point where it is connected to the base for a shaft, 0, turningin bearings D upon the upper surface of the base. This shaft is providedwith a rigid and a loose pulley, E and F, upon its outer end, whichpulleys may be rotated by the driving-power, and with a pulley, G, 'ashort distance inside the fast and loose pulleys. 'A treadle, H, ispivoted at its inner end to the under side of the base-plate, projectingat-the front of the same, and the lower end of a rod, I, .is hinged tothe said treadle, passing up through a-vertical perforation, J, in theupright post or column, and Sliding in the same. The upper end of thepost or column forms a table, K, having a rearwardly-projecting arm, L,forming upwardly-projecting lips M upon its outer end, between which theend of an arm, N, is pivoted, which arm is guided to move in a verticalplane by means of two upright guides, O, fitting into two recesses, l?P, one upon each side of the arm at about its middle. The uphorizontalshaft.

per end of the vertically-sliding rod is secured end, and the arm beingraised by means of spiral springs Q, near its rear end, and R, aroundthe upper end of the sliding rod, bearing with its lower end against awasher, S, restingupon the edges of a notch, T, in the front edge of thetable, may be depressed by depressing the treadle. The outer end of thearm has ahorizontal longitudinal slot or recess, U, and the outer edgesof the lips V, formed by the said recess, are provided with two verticalbearings, in which turns a shaft, W, provided with a pulley, X, fittingbetween the lips into the recess, with a weight, Y, at its upper end,and with a bell or cone shaped block, Z, at its lower end, the underside of which block is plane, and provided with a circular file orgrinding-disk, A. A belt, B, passes over the inner pulley upon the lowerhorizontal shaft, over two guide-pulleys, 0, one upon each side of thehinged arm near its fulcrum, and over the pulley upon the grinder-shaft,sothat the grinder-disk may be revolved by the lower A shoe-jack, D, ishinged upon the base near its front edge, consisting of a lowerbifurcated end, E, which is hinged to the base, and straddles thebearingof the lower shaft, a central portion, F, turning with its lower reducedend, G, in a bore, H, in the top of thebifurcated end, and having anaxial bore, I, in its upper end, in which the lower reduced end, J, ofthe foot K, of the jack slides, and is secured by a set-screw, L. Theboot is placed upon this jack, and ,a clamp, M, consisting of" an innerblock, N, having its'forward edge slightly concaved, and two slightlyinwardly-curved springs, 0, serves to clamp the counter of the same andhold it in place when the grinder-disk is brought to bear against theheel or sole of the shoe by depressingthe treadle.

It will be seen th. tthe shoe-jack by its construction may be adjustedtohold the boot in any position and at any height, and that the beltdriving the grindershaft will be tightened when the arm is depressed,overcoming the increased friction by the grinder-disk bearing againstthe bottom of the shoe, and that the heel of the shoe, being heldperfectly true by the clamp holding the Shoe, will be ground perfectlytrue by the disk 'to the under side of this arm near its outer:

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- 1. The combination of an adjustablehinged shoe-jack, a clamp consisting ofan inner block and twoforwardly-proj ecting inwardly-curved springs, and a grinding-diskadapted to be brought down to turn in a horizontal plane, as and for thepurpose shown and set forth.

2. lhe combination of an upright frame, a shoe-jaek hinged at its lowerend to the lower end of the frame, a clamp secured near the upper end ofthe frame, an arm hinged at one end upon the upper end of the frame,forming a bifurcated arbor at its outer end, swinging between verticalguides, and adapted to be de-
